A ballpark sells two types of tickets: a reserved seat for $13 and a box seat for $19. Yesterday, the ballpark sold a total of 2620 tickets for a total of $39820. Write the system of equations to find the number of reserved seats and box seats sold. Let x be the number of reserved seats sold and y be the number of box seats sold. Do not solve.
Evaluate the function below at x = 7. Put your answer in function notation.
h(x) = 3x – 6
h(7) =
To evaluate the function ( h(x) = 3x – 6 ) at ( x = 7 ), you will substitute 7 for ( x ).
Here’s the step-by-step process:
1. Substitute ( x ) with 7 in the function:
[
h(7) = 3(7) – 6
]
2. Calculate ( 3(7) ):
[
3(7) = 21
]
3. Now, subtract 6 from 21:
[
21 – 6 = 15
]
Therefore, ( h(7) = 15 ).
So the answer is:
[ h(7) = 15 ]
This means that when you input ( 7 ) into the function ( h(x) ), the output is ( 15 ). If you have any more questions or need further assistance, feel free to ask!
